Light-emitting diode lamp

摘要

An LED lamp (100) including a lamp housing (110), an LED light source (120), a heat sink (130) and a control circuit (140). The lamp housing (110) has an accommodating space (110a), a plurality of air inlets (110b) and a plurality of air outlets (110c), wherein the accommodating space joins an environment through the air inlets and the air outlets. The LED light source (120) and the heat sink (130) are disposed in the accommodating space (110a) and the heat sink (130) is connected with the LED light source (120). The heat sink (130) includes a pedestal and a plurality of heat dissipation fins connected to the pedestal. An air convection channel is located between any two adjacent heat dissipation fins. Air from the environment flows into the accommodating space (110a), passes through the air convection channel, and leaves the accommodating space via the air outlets sequentially. The control circuit (140) is disposed in the accommodating space (110a) and connected to the LED light source (120).
